Abstract
Description
Technical Field
[0001] The utility model relates to a railway double-side roadbed drainage mechanism. Background Art
[0002] Rail transport is a land transport mode in which locomotives pull train vehicles on two parallel tracks.
[0003] At present, many railway roadbeds are equipped with drainage covers on both sides. The drainage covers are connected to the drainage channels. There are drainage holes on the drainage covers. Rainwater accumulated on the rails can pass through the drainage holes into the drainage channels and then be discharged outward. However, when the precipitation is too heavy, the drainage holes on the drainage covers are difficult to drain the rainwater quickly, which can easily cause rainwater to accumulate on the rails and affect driving. Summary of the invention
[0004] The technical problem to be solved by the utility model is to provide a railway double-side roadbed drainage mechanism with fast drainage speed.
[0005] The above object is achieved in this way: it includes a closing plate, which is arranged on the top of the drainage channel. There are drainage channels on the roadbed on the left and right sides of the rails, and the outer side of each drainage channel is connected to a plurality of drainage pipes.
[0006] The closing plates on the two drainage channels have the same structure, that is, a positioning groove is provided on the upper surface of each closing plate, a through hole is provided at the bottom of the positioning groove, a drainage cover is located in the positioning groove, and a plurality of drainage holes are provided on the drainage cover.
[0007] A control component is installed on the closing plate, and the control component includes a protective shell, the bottom of the protective shell is fixedly connected to the top of the closing plate, a motor is fixedly installed inside the protective shell, and two threaded rods are also arranged inside the protective shell, both of which are connected to the internal threads of the drain cover, and the bottom ends of the two threaded rods are rotatably connected to the bottom of the positioning groove, and synchronous pulleys are provided at the output end of the motor and the top ends of the two threaded rods, and a synchronous belt is connected between the three synchronous pulleys.
[0008] A signal receiver is also fixedly installed inside the protective shell, and the output end of the signal receiver is electrically connected to the motor. A battery is fixedly installed inside the protective shell, and the output end of the battery is electrically connected to the motor.
[0009] Piezoelectric ceramic components are installed on the left and right sides of the rail respectively, and the two piezoelectric ceramic components are electrically connected to the batteries in the two control components through transmission lines respectively.
[0010] The advantages of the utility model are:
[0011] During the use of this device, when the rainfall is heavy, the staff can send radio waves carrying information about excessive rainfall through the remote terminal equipment. After receiving the radio waves, the signal receiver transmits them to the motor in the form of electrical signals. After receiving the electrical signals, the motor pulls the threaded rod through the synchronous pulley to rotate around its own axis. While the threaded rod rotates, the drain cover is pulled to move vertically upward synchronously. The drain cover is disengaged from the positioning groove, and the rainwater directly passes through the penetration opening into the drainage channel and is discharged outward from the drain pipe. This design solves the shortcomings of the existing technology, effectively avoids the problem of drainage difficulty when relying solely on the drainage holes on the drainage cover when the rainfall is heavy, and improves the drainage speed.
[0012] When a train runs on top of the rails, the rails will vibrate, and the vibration of the rails will pull the piezoelectric ceramic components to vibrate together. The piezoelectric ceramic components generate electrical energy during the vibration process. This electrical energy is transmitted to the battery through the transmission line for storage. The electrical energy stored in the battery is used to power the motor. This design can effectively convert the vibration energy of the rails into energy for the motor operation, reducing energy consumption. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Combine the following Figure 1-4 Further explain the utility model;
[0018] It includes a closing plate 1, which is arranged on the top of a drainage channel 8. There are drainage channels on the roadbed on both sides of the rail 9, and the outer side of each drainage channel is connected to a plurality of drainage pipes 10;
[0019] The closing plates on the two drainage channels have the same structure, that is, a positioning groove 2 is provided on the upper surface of each closing plate, a through hole 3 is provided at the bottom of the positioning groove, a drainage cover 4 is located in the positioning groove, and a plurality of drainage holes 5 are provided on the drainage cover. The transition portion between the rails and the closing plates is a slope, and rainwater accumulated on the rails can move along the slope and then pass through the drainage holes to drain into the drainage channel, and then be discharged outward through the drainage pipe.
[0020] A control component 6 is installed on the closing plate, and the control component includes a protective shell 61. The bottom of the protective shell is fixedly connected to the top of the closing plate, and a motor 62 is fixedly installed inside the protective shell. Two threaded rods 63 are also arranged in the protective shell. The two threaded rods are connected to the inner threads of the drain cover, and the bottom ends of the two threaded rods are rotatably connected to the bottom of the positioning groove. Synchronous pulleys are provided at the output end of the motor and the top ends of the two threaded rods. A synchronous belt 64 is connected between the three synchronous pulleys. The synchronous pulley can convert the output power of the motor into the rotational force of the threaded rod. The rotation of the threaded rod can drive the drain cover to move in the vertical direction.
[0021] A signal receiver 65 is also fixedly installed inside the protective shell, and the output end of the signal receiver is electrically connected to the motor. A battery 66 is fixedly installed inside the protective shell, and the output end of the battery is electrically connected to the motor. The user can send radio waves carrying information through a remote terminal device. After receiving the radio waves, the signal receiver transmits them to the motor in the form of an electrical signal, and the motor can operate after receiving the electrical signal.
[0022] Piezoelectric ceramic components 7 are installed on the left and right sides of the rail respectively, and the two piezoelectric ceramic components are electrically connected to the batteries in the two control components through transmission lines respectively.
[0023] Working principle: In actual operation, when a train runs on the top of the rails, the rails will vibrate. The vibration of the rails will pull the piezoelectric ceramics to vibrate together. The piezoelectric ceramics generate electrical energy during the vibration process. This electrical energy is transmitted to the battery through the transmission line for storage. The electrical energy stored in the battery is used to power the motor.
[0024] When the rainfall is normal, the rainwater accumulated on the rails will move along the slope on the roadbed to the top of the closed slab layer, pass through the drainage holes on the drainage cover into the drainage channel, and then be discharged outward through the drainage pipe.
[0025] When the rainfall is heavy, the staff sends radio waves carrying information about excessive rainfall through the remote terminal equipment. After receiving the radio waves, the signal receiver transmits them to the motor in the form of an electrical signal. After receiving the electrical signal, the motor pulls the threaded rod to rotate around its own axis through the synchronous pulley. While the threaded rod rotates, the drain cover is pulled vertically upward synchronously, and the drain cover is detached from the positioning groove. At this time, rainwater directly passes through the perforated holes into the drainage channel and is discharged outward from the drain pipe. When the rainfall returns to normal, the staff sends radio waves carrying information about normal rainfall through the remote terminal equipment. Similarly, after receiving the radio waves, the signal receiver transmits them to the motor in the form of an electrical signal. The motor reverses and pulls the threaded rod to rotate in the opposite direction around its own axis, and the drain cover returns to the positioning groove.
[0026] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
